Virgos have a tendency to try to do everything perfectly, so should hone self-compassion when they slip up. Ms Knowles advises people of this star sign to go organic to avoid allergies

VIRGO (August 24-September 23)

Making lists is something Virgoans are very good at as you are practical and methodical in your approach.

Your diet is very important to you at all times but if you are embarking on a special dietary regime, keep a food journal, plan everything you are intending to eat by listing its nutritional value and benefits to your health.

The 'quickie get results in a week' type of diet will not work for Virgos, who want to reach beyond easy solutions

The ‘quickie get results in a week’ type of diet is not for you as you are discerning and want to reach beyond easy solutions.

You also have an innate awareness of the connection between your mind and your body.

The difficulty for you will be your tendency to try to do everything perfectly.

Don’t be too hard on yourself if you slip up.

Tip: Go organic to avoid allergies. Virgo rules the skin, which is often prone to allergies, and so theese people need to avoid additives or pesticides in their food.

LIBRA (September 24-October 23)

There are so many diets out there it may be difficult for Librans to actually decide which one to choose.

Once you do decide, you may be tempted to switch to another one which might just be better – or will it?

The motivation is definitely there for you as the idea of monitoring your eating habits so that you have nutritional balance is very appealing, especially if the outcome makes you even more physically attractive.

Try dieting with your BFF so that you can share experiences. Choose a plan that will balance you internally.

Libra rules the kidneys and these people are prone to diabetes. The correct potassium levels keep the kidneys healthy.

Becoming physically attractive as well as eating a nutritional balance is appealing to Libras. They should choose foods rich in potassium, like bananas, leafy greens, fish and yoghurt

SCORPIO (October 24-November 22)

Scorpios have stronger will-power than any other sign and so once you decide on a diet you are almost certainly going to stick to it.

Scorpios will willingly undertake a strict, painful fast if they see a transformation at the end

Having perseverance, determination and a strong sense of purpose means you are excellent at controlling your impulses.

You will willingly undertake a strict, painful fast if you feel there is transformation at the end of it.

You may not tell others what you are undertaking and will smile enigmatically when they say how well you’re looking, enjoying your secret.

Tip: Remember to include enough roughage in your diet. Scorpio rules the bowels and these people often suffer from constipation, hence the need for a high fibre diet.

SAGITTARIUS (November 23-December 22)

Abstinence is difficult for Sagittarians, who are prone to success. 'Creanm salt and sugar all have healthier substitutes,' Ms Knowles says

Sagittarians like to set goals and enjoy a challenge but may lose heart if results don’t happen quickly.

You rarely do things by half and will enthusiastically throw yourself into a new diet with optimism.

However, abstinence may be difficult for you as you are prone to excess.

Be realistic about what you can achieve on a weekly basis and incorporate plenty of exercise and fun into the regime. No need to overdo it.

Tip: Cream, salt and sugar all have healthier substitutes. Sagittarius rules the liver and too much rich food can make these people feel very out of sorts.

CAPRICORN (December 23-January 19)

Working steadily towards a target works best for Capricorns.

You won’t be looking for an easy overnight success; the more difficult the regime, the more satisfied you will be once you achieve it.

Testing your tenacity and perseverance comes naturally and you can survive deprivation if there is an end in sight.

Aquarians, who are attracted to quirky ways of doing things, should swap alcohol for ginger beer

Don’t be too hard on yourself - healthy eating can be a pleasure and a diet doesn’t have to be an endurance test.

Try disciplines such as aerobics, Tai Chi or weights.

Tip: Calcium is particularly important for you. Capricorn rules the teeth and skeletal system, so calcium is vital to keep these healthy.

AQUARIUS (January 20-February 19)

Aquarians are attracted to quirky, unusual ways of doing things.

You are an innovative and original thinker and ideally you could select a regimen and then individualise it so that it is different from the norm.

If you get bored or lose interest you will drop the diet without a backward glance.

However, if you begin to adopt it as a way of life, you will stick to it like glue, resisting suggestions that you have gone far enough.

Moderation is the key, know when to stop.

Tip: Replace alcohol with ginger beer. Aquarius rules the circulatory system, which is kept healthier by avoidance of too much alcohol but stimulated by ginger.

PISCES (February 20-March 21)

Those born under the sign of Pisces dream of perfection, but finding a foolproof diet may not be easy and sticking to it might be even harder for you.

Sometimes your feelings can be so overwhelming that having boundaries about what you eat and when you eat seem impossible.

Therefore, under-eating can be as much of a problem for you as over-eating.

Try bringing dance, yoga or meditation into your daily schedule as these are good ways for you to express locked-in emotions.

Tip: Keep up your fluid intake as sometimes you eat when you are thirsty. Pisces rules the pituitary gland and Pisceans are prone to holding onto impurities which need regular flushing out with fluids.

Pisceans ought to drink more fluid, as sometimes they eat when they are thirsty. They are sometimes over-emotional and could try dance, yoga or meditation in order to express locked-in emotions, says Gillian
